How to Preserve Your Brand’s Human Voice in the AI Era

The Seed Cathedral: A Metaphor for Modern Brand Storytelling

When Thomas Heatherwick’s studio designed the UK Pavilion for the Expo 2010 Shanghai, they went big. They created the Seed Cathedral, a huge, rounded box covered in 60,000 acrylic rods. Suspended inside the tip of each rod were seed varieties chosen with help from the Millennium Seed Bank at Kew Gardens. There were 250,000 seeds in all, an amazing representation of Britain’s biodiversity. At night, LEDs lit up the rods; during the day, they shone in the sun. 

For brand leaders challenged with getting the right mix of human- and AI-generated content today, the Seed Cathedral is the ideal metaphor. If you want your brand to shine now and in the future, preserve your human-created content. It contains the seeds of your brand’s human voice, values, and vision. 

Why Human-Created Content Still Matters

The role of human-created content is changing, and while it may often be AI-assisted now, it hasn’t suddenly become disposable. It is and will remain valuable intellectual property. The seeds of human-originated content are the baseline for emotional connection and brand trust, not to mention insurance in case your brand is ever at risk. The smart-money CMOs are preserving this investment, and also planning to put it to use for future AI training, referencing, repurposing, and more. 

Your Brand DNA: More Than Data Points

Human-created content is never more important than when you’re first deciding and communicating what your brand stands for and believes in. Establishing your brand DNA is not a mechanical exercise and should never become one. This process relies on intention, taste,  judgment, and the uniqueness that makes your brand stand out. Brands have invested in years of carefully considered content and other sales and marketing creative—from teams of experienced writers, editors, designers, marketers, strategists, and product experts—for a reason. And it’s not just because AI didn’t exist yet. It’s because humans are able to actually talk to leadership, creatives, and sales and product teams, to weave together their visions, concerns, and priorities. Human insight, perspective, personality, and nuance shape authenticity. And authenticity builds trust, the lifeblood of a brand.

The Power of Being Quirky

Brand DNA is the soul of a business, and it’s not algorithmic—it’s quirky. Memorable. Like our own DNA and its effects. This is a good thing, because being distinct increasingly matters in a world where, as one comedian recently put it, AI is “making us all just a little more basic.” As most of us can attest, the homogenization of AI-assisted content can come off as both dull and direct, or, as The New Yorker’s Kyle Chayka put it, “Averageness is efficient.”

So, of course, AI can extend, refresh, and repurpose the seeds of your brand DNA once they’re planted. AI tools can be the water and sunlight—they’re excellent at that, especially for content creation at scale. Got an impossible-sounding idea? AI tools can make it happen, creating campaign pilot content without prohibitive risk (or time and money). Got two ideas you want to A/B test quickly for impact? Done. It can optimize on the fly, personalizing your brand messaging for individual customers. It can atomize one piece of content into all sorts of formats with the same voice and localize content with the right language tone and visuals. And it can do it fast. 

AI as The Water and Sunlight for Your Brand Seeds

We know AI tools support content experimentation and creation at scale. But that content still relies on human judgment to determine: Is this good? Judgment becomes ever more important in a saturated marketplace. So, today, CMOs who treat human-created content as a long-term asset outperform those who treat it as disposable. It helps them secure their brand, continue to stand out, and withstand the risks of AI error. 

These CMOs understand that emotional ROI is ROI, and it reflects well on them if they maintain it. If stories make information 22 times more memorable than stats alone (63% of people remember stories from presentations; only 5% remember the data), you have to keep telling them. If the emotional connection created by stories means a higher gross margin and more annual growth, you have to keep delivering it. And there’s still the best way to do both. The National Newspaper Association reported on Ipsos research that humans prefer content of all kinds created by humans instead of AI. It resonates more. 

Search Engines Still Reward the Human Touch

No surprise that search engines evaluating content quality continue to prioritize human-created or -influenced content. Research shows “pages with strong E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) signals have a 30% higher chance of ranking in the top 3” results. And Google’s E-E-A-T guidelines prioritize content with genuine human insight and expertise. Human-authored content still shows a remarkable ability to improve keyword rankings, outpacing AI and hybrid content by a long shot. Human-generated content outperforms AI in user engagement, too.

How to Preserve Your Brand’s Seed Library

So what to do? Treat your original, human-created brand creative like a treasured packet of seeds: organize, preserve, and grow it with care. First, inventory all of it, from DNA documents, taglines, and voice and tone guidelines, to style guides, color palettes, and imagery. Next, curate it. What still works? What can be archived? 

Create a legacy library that is labeled and accessible to protect and preserve your institutional knowledge, your core DNA. Extract from that the essential pieces you want to amplify. Then repurpose it as needed, adjusting for current needs, different formats, and new distribution channels. You can also use it to train your AI, creating a master reference compilation for internal prompts.

Looking Back to Move Forward

We don’t yet know how much content, in the future, should be human-originated, human-originated and AI-assisted, and entirely AI-generated. But it’s up to us. So it pays for CMOs to look both backwards and forwards. You’ve already invested in creating your seed cathedral of human-generated content. Now is the mission-critical time to preserve it for your brand’s future.
